ROBERT MAHCHER, OF NEW' YORK, N. Y.

MACHINE FOR ENAMELING MOLDING'S.

Specification forming part of Letters Patent-N0. 24,879, dated July 26,1859; Reissued April 3, 1860, No. 94o.

To all whom it may concern:

Be it known that I, ROBERT MARCHER, of the city, county, and State ofNew York, have invented a new and useful Improvement in Machinery forEnameling Moldings; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe anneXed drawings, making a part of this speciication, in which-Figure 1, is a longitudinal vertical section of my invention taken inthe line Fig. 3. Fig. 2, a transverse vertical section of ditto, takenin the line y, y, F ig. 3. Fig 3, a plan or top view of ditto. Fig. 4, atransverse section of the vibrating bed and dog taken in the line s, e',Fig. 3, and showing one form of feeding' device that may be used.

Similar letters of reference indicate corre# sponding parts in theseveral figures.

This invention relates to an improvement on a machine for enamelingmoldings, for which Letters Patent, and a re-issue thereof were grantedto me, respectively bearing date October 21st 1851, and March 15th 1859.

The within described invention consists in an improvement in the hopperwhich contains the necessary composition for enameling, whereby thehopper is rendered capable of expanding and contracting to compensatefor the inequalities of the molding.

The invention further consists in the adaptation of feeding devices ashereafter shown and described which permit of the employment or use ofany power as a motor.

To enable those skilled in the art to freely use, understand andconstruct my invention I will proceed to describe it.

A represents a framing, which may be of rectangular form and constructedin any proper manner `to support the working parts. On the upper part ofthe framing A and at its back end a hopper B is placed which containsthe usual composition C that is applied to the molding. This hopper B isformed of five parts, to wit, two yielding sides a a, two end pieces b band a bottom c. The bottom c is provided with two ledges c c betweenwhich the molding D passes, and the end pieces l Z/ have each a recessmade in them corresponding inversely with a transverse form of themolding, so as to allow the latter to pass through the hopper.

The end piece b serves merely as a guide, but the outermost end piece bserves as a scraper to regulate the supply of composition on the moldingand give the same its proper form and finish as the molding passesthrough the hopper. The end piece may be adjusted at any desired heightby set screws. The molding D, when the machine is in use, forms,strictly speaking, the bottom of the hopper, and the composition C restsupon it as shown clearly in Fig. 2. The end pieces ZJ b are arrangedsubstantially like those in the patented machine previously alluded to,and therefor do not require a more minute description. The side pieces aa, however, are of novel construction, and are each formed of two partsa a connected by a joint d, the lower end of the plate a being attachedby joints, e, to blocks, f, which are attached to the framing by screwsg. To each block, f, an upright, h, is attached, and in each upright ascrew, z' is fitted, the ends of said screws bearing against the partsa. See Figs. 2 and 3. The standards z., may be made yielding instead ofstili as represented in the drawing; so as to exert a slight lateralpressure on the parts or side pieces a, a, and thus avoid any rigidcontact between the parts and the article being operated upon. The loweredges of the parts c. of the side pieces a are grooved longitudinallyand fit on the upper and lower corners of the molding as shown clearlyin Fig. 2, said parts acting in connection with end piece b as keepersto retain the molding in proper posit-ion as it passes through thehopper.

From the above description it will be seen that as the molding, D,passes through the hopper, B, the sides, a a, will yield or give andthereby conform to any irregularities of surface which the molding mayhave. This will be fully understood by referring to Fig. 2.

In the upper part of the framing, A, a reciprocating bed, E, is placed,and allowed to slide freely back and forth. This bed, E, has itsreciprocating movement given it by means of a connecting rod, F, whichis attached to a crank wheel, G, that is secured to one end of ahorizontal shaft, I-I, at the front end of the framing, A. This shaft,H, has two bevel wheels, I, I, placed on it; said wheels gearing intocorresponding wheels, J, J, which are placed on the lower end of thevertical shafts, K, K', on the upper parts of which feed rollers, L, L',are

placed, to the lower ends of which two other wheels, M, M', areattached. The wheels, M, M', gear into corresponding wheels, N, N', onthe upper part of the framing, and these wheels, N, N', gear intowheels, O, O', which are attached to the lower part of feed rollers, P,P'. This system of wheels is shown clearly in Fig. 3. The feed rollers,L', P', and connecting wheel, N', with their respective shafts areconnected with a laterally sliding bed, Q., at the front part of theframing, and the lower end of the shaft, Ii', of the roller, L', isstepped in a bar which is attached to the bed, Q. By this arrangementthe feed rollers, L', P', are allowed to yield -or give, and springs, j,are attached to the bed, in order to keep said rollers, L', P', to theirwork.

To the framing, A, and directly in line with the space between the feedrollers, a bearing plate or block, R, is placed. This plate or block isattached to a suitable 'support and its lower end is made of such formas to correspond inversely with the transverse Aform of the molding, D.

To the upper surface of the bed, E, a dog, S, is attached by a pivot,la, the dog being allowed to work freely on its pivot. The bearing edgeof this dog is designated by Z, and the dog has a horizontal projectingplate, m, attached which projects beyond a fence, n, on the bed, E. Tothe upper part of the framing, A, at one side two vertical, adjustableplates, 0, 0', are attached by screws, p, p, and to the opposite side a1 spring-catch, g, is attached as shown clearly 1n Fig. 3.

The operation is as follows Power is applied to the wheel G, in anyproposed way, and a rotary motion is communicated to the feed rollers,L, L', P, P', by the gearing described, and a reciprocating movement iscommunicated to the bed, E, by the connecting rod, F. The molding, D, isfed along by the feed rollers underneath the bearing plate, R, andbetween the dog, S, and fence 1i, and if heavy or large moldings are tobe enameled the rollers, L, L', P, P', serve merely to feed the moldingto the dog, S, which serves to feed the molding during its progressthrough the hopper B. The dog,

S, grips the molding, D, during the forward movement of the bed, E, andfeeds it along'through the hopper, the dog being released at thetermination of the forward movement of the bed E, by the plate 0. At thetermination of the backward movement of the bed, E, the dog, S, isslightly actuated by the plate 0', but not suiiciently to cause the dogto grip the molding D, the remaining movement being given the dog by thespring-catch, g, which effects the result, just after the commencementof the forward movement of bed E. By this arrangement no retrogrademovement is allowed the molding, D, a contingency which would be liableto occur if the dog, S, were actuated by the plate o', for the dog wouldnecessarily grip the molding a little before the termination of thebackward movement of the bed, and the work of enameling would be marredto a certain extent by such a result.

In enameling light moldings the feed may kbe given by the rollers, L L',P, P', for the power required is not great and the rollers would becompetent to do the work; but in enameling heavy moldings the rollerswould be inefficient when used alone. They would, however, in the lattercase, be valuable to feed the moldings to the dog, S, and thereby saveconsiderable labor.

I do not claim broadly a hopper, B, through which the molding, D,passes, for this has been used and was formerly patented by me, aspreviously alluded to; neither do I claim the feed movements as hereindescribed, when separately considered, for they have been previouslyused, but

I do claim as new and desire to secure by Letters Patent,

l. The elastic or yielding sides a, a, of the hopper B, arranged. tooperate substantially as, and for the purpose, set forth.

2. In combination with the hopper, B, the reciprocating dog, S, attachedto the bed, E, and operated as shown, and also, in combination with saidhopper the feed rollers, L, L', P, P', either or both feeding devicesbeing employed for the purpose specified.

ROBT. MARCHER.
